Getting a Grasp on Chromates

UTC is serious about sustainability. And part of that is getting a grasp on chromates - hazardous substances that are on the EU's REACh list of regulated chemicals.

To that end, the REACh Program Office and Engineering were delighted to host the third UTC-wide chromate alternatives workshop May 21 - 23, 2018 in Windsor Locks, Connecticut.

Associates from around UTC - including Pratt & Whitney - East Hartford; Pratt & Whitney - Canada; the United Technologies Research Center (UTRC); and five of our own SBUS gathered to go over the latest on alternatives to conversion coat and chrome plate.

Teammates from 10 of our sites, including Wolverhampton, UK; Vernon, France; Oakville, Canada; Windsor Locks, Connecticut; Westford, Massaschusetts; Rockford, Illinois; Troy, Ohio; Burnsville, Minnesota; Bangalore, India; and Uniontown, West Virginia, took part

Representatives from 3 UTC business units presented the work they've accomplished as well as Technology Readiness Level (TRL) status, including gaps.

What did they accomplish? Here's a list of the group's goals:

  • Re-establish the conversion coat and hard chrome plate baselines by following the lessons learned from the GRASP3 Team (GReen Anodize, Seal, Prime and Paint Process)
  • Institute TRL progression combinations of base materials and alternate coatings by leveraging PW/PWC/UTRC/Cross-SBU-UTAS experience to establish a TRI progression
  • Identify collaborative test opportunities across UTC bsuinesses
  • Ensure results are shared across UTC divisions
  • Revise Cadmium Alternates Guideline
  • Prioritize next Material of Concern (MoC) TRL progression candidates.
